Nielsen, an entity best known for its television ratings system, announced Wednesday that it will begin to track what you do with your cell phone.
In particular, the company will begin measuring how consumers use mobile Internet and mobile video beginning in July.
The service will be called Nielsen Wireless.
Included in the metrics will be comparisons of how subscribers of different wireless carriers watch TV or play video games, compared to the same use on their cell phone.
One tidbit the company has already released is that 55 percent of users of video-enabled mobile phones are from households with total incomes of $75,000 or greater.
